The talismanic quality of this stone is an important element in its popularity, as it is supposed to bring good fortune and physical well-being to the wearer and to afford protection against contagion. The Tibetans share in the quite general belief that the turquoise will grow pale in sympathy with the present or prospective fortune and health of the person wearing it, and as a loss of color is considered portentous of coming evil, such stones are gotten rid of as soon as possible to be replaced by those of a brighter hue. The dealers who buy up for a trifling sum these discolored turquoises often treat them with a dose of blue dyestuff which superficially restores the color, and it is stated that many of the soldiers of the British expeditionary force to Tibet in 1904 were at first deceived into buying these vamped-up stones, but they soon discovered the deception and were more careful later on. Turquoises are also believed to guard against the Evil Eye, and a quasi-sacred character is lent to some especially fine specimens by setting them in the foreheads of statues of the Buddha or other religious images.[608] The women of Tibet are said to prize most highly as amulets pieces of cloth adorned with turquoise or coral, which they have acquired from the Lamas, who by the imposition of their priestly blessing have endowed these objects with a peculiar sanctity in the eyes of the Tibetan devotees. Another amulet favored in this far-off land is a small metal box of gold, silver, or copper, and encrusted with turquoise. Within are enclosed little scrolls inscribed with mystic characters to conjure evil spirits and thwart their malevolent schemes for the tribulation of mankind. An ingenious, if rather far-fetched explanation of the supposed power of coral to avert lightning and hail is given by Fortunio Liceti. In his opinion, coral, being of a warm quality, overcomes the coldness of the atmosphere, which produces lightning by the attraction of contraries, and hail by its own quality. This is a specimen of the attempts to find a plausible physiological reason for the powers of gems, the writers never for a moment hesitating to accept the popular beliefs in this respect.[609] [Illustration: “THE LIGHT OF THE EAST” Mural fresco painting by Albert Herter, in the Hotel St. Francis, San Francisco, California.

Here as in so many other parts of the world, the amulet is believed to acquire especial efficacy when worn in this way, as it comes in immediate contact with the person of the wearer.[610]
